The SM30T47AY is a unidirectional Zener TVS diode from STMicroelectronics designed for automotive applications. It features a reverse standoff voltage of 40V, a breakdown voltage of 47V, and a maximum clamping voltage of 64.5V.
With a peak pulse power dissipation of 3000W (3kW) under 10/1000µs waveform, it can handle a peak pulse current of up to 43.5A. The device does not provide power line protection, focusing on transient voltage suppression for signal lines.
The diode is housed in a DO-214AB (SMC) surface-mount package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 175°C, making it robust for harsh environments.
Typical applications include automotive electronics, such as engine control units, sensors, and infotainment systems, where protection against voltage transients is required. The part is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited).
